Abstract: A switching regulator includes a boost power stage circuit and a control circuit. The boost power stage circuit includes: at least one power switch configured to switch a terminal of an inductor according to an operation signal during a normal operation period, such that the terminal of the inductor is switched between an output voltage and ground level; and a power line switch connected in series to the inductor between the input voltage and the output voltage. The power line switch is turned OFF when the output voltage is short to ground level, to prevent a short current from flowing from input voltage to ground level. The control circuit generates the operation signal according to the output voltage and determines whether the power line switch is P-type or N-type MOS device, so as to turn OFF the power line switch when the output voltage is short to ground level.

Abstract: An object location guiding device and an operation method thereof are provided. The object location guiding device includes a processor, a controller and a guiding element array. Guiding elements of the guiding element array are disposed at different positions in a field so as to point to storage positions of different objects in the field. The processor converts the object data on an object list into storage-position information. The controller receives the storage-position information from the processor, converts the storage-position information into a first axis position code and a second axis position code, and drives the guiding element array by using the first axis position code and the second axis position code, so as to allow at least one corresponding guiding element of the guiding elements to point to a storage position of a corresponding object in the field.
